The problem is in ConfigurationOfRPackage as in #ensureMetacello� is like this:
ensureMetacello
��� Smalltalk at: #MetacelloProject ifAbsent: [
��� ��� Gofer new
��� ��� ��� ��� disableRepositoryErrors;
��� ��� ��� ��� url: '
http://seaside.gemstone.com/ss/metacello';
��� ��� ��� ��� package: 'ConfigurationOfMetacello';
��� ��� ��� ��� load.
��� ��� (Smalltalk at: #ConfigurationOfMetacello) project latestVersion load: #('default' 'UI') ]
�
If you see, it is loading #('default' 'UI')� of metacello..... UI -> OB.
change that to #('default') and wala
BTW, I would use the latest recommended #ensureMetacello:
